The embedded brains GmbH & Co. KG is the legal successor of embedded
brains GmbH.

|
Updates #3053.
|
|
Updates #4625.
|
|
Use the following variant which was already used by most source files:
#ifdef HAVE_CONFIG_H
#include "config.h"
#endif
|
|
|
|
Add and use rtems_libio_exit_helper. Add rtems_libio_exit().
The fclose(stdin) etc. makes no sense during exit. This would use the
_REENT structure of the thread calling _exit().
|
|
Add and use rtems_libio_helper function type. Add and use
rtems_libio_helper_null() instead of NULL pointer.
|
|
|
|
|
|
Add CPU port type CPU_Exception_frame and function
_CPU_Exception_frame_print().
The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh,
sparc64, and v850 use an empty default implementation of
_CPU_Exception_frame_print().
Add rtems_exception_frame and rtems_exception_frame_print().
Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal()
with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc,
and sparc for unexpected exceptions.
Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the
BSP_PRINT_EXCEPTION_CONTEXT define used in the default
bsp_fatal_extension().
Add test sptests/spfatal26.

This reduces code size and provides a function similar to fputc().
|
|
New defaults rtems_filesystem_default_fsync_or_fdatasync() and
rtems_filesystem_default_fsync_or_fdatasync_success() for fsync_h and
fdatasync_h. The rtems_filesystem_default_fsync_or_fdatasync() sets now
errno to EINVAL according to POSIX.

o A new data structure rtems_filesystem_global_location_t was
introduced to be used for
o the mount point location in the mount table entry,
o the file system root location in the mount table entry,
o the root directory location in the user environment, and
o the current directory location in the user environment.
During the path evaluation global start locations are obtained to
ensure that the current file system instance will be not unmounted in
the meantime.
o The user environment uses now reference counting and is protected
from concurrent access.
o The path evaluation process was completely rewritten and simplified.
The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation
method. Recursive calls in the path evaluation have been replaced
with iteration to avoid stack overflows. Only the evaluation of
symbolic links is recursive. No dynamic memory allocations and
intermediate buffers are used in the high level path evaluation. No
global locks are held during the file system instance specific path
evaluation process.
o Recursive symbolic link evaluation is now limited by
RTEMS_FILESYSTEM_SYMLOOP_MAX. Applications can retrieve this value
via sysconf().
o The device file system (devFS) uses now no global variables and
allocation from the workspace. Node names are allocated from the
heap.
o The upper layer lseek() performs now some parameter checks.
o The upper layer ftruncate() performs now some parameter checks.
o unmask() is now restricted to the RWX flags and protected from
concurrent access.
o The fchmod_h and rmnod_h file system node handlers are now a file
system operation.
o The unlink_h operation has been removed. All nodes are now destroyed
with the rmnod_h operation.
o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system
operations.
o The path evaluation and file system operations are now protected by
per file system instance lock and unlock operations.
o Fix and test file descriptor duplicate in fcntl().
o New test fstests/fsnofs01.
